OpenJDK 17 is here, with a range of new features and enhancements. Join in with the friends of OpenJDK, who provide a free central resource for all things Java at Foojay.io, in celebrating the OpenJDK on the Foojay Virtual OpenJDK 17+ JUG Tour, including at KnoxJava with Carl Dea!”

Abstract:
As a Java developer, you may have a need to access native libraries, such as Tensorflow, SqlLite, ffmpeg, OpenGL, but later find that JNI is your default choice. JNI (Java Native Interface) requires native code to be installed. You’ll quickly find that JNI wrapper code is difficult to maintain.

New to OpenJDK 17 is the Foreign Linker API (JEP 389) as a replacement for JNI to provide a pure-Java solution and perform comparable to, or better than, JNI.

The aim of this talk will be to provide a friendly introduction to OpenJDK 17’s Foreign Linker API.
